Are you running headers? You might want to consider running a remote solenoid to keep away from the heat... I can't comment on brand etc... I've had the original solenoid plus a remote one since I put the car together...
Went to napa yesterday, no solenoid, wanted $35, said they only sell complete starters. And to boot they didn't have starters. Went to crappy tire, $20 later, had solenoid in hand. Did you know there are long and short ones? I didn't know this.
Andrew. Good idea on the remote solenoid. I have been thinking about it. Battery is being located to trunk. Been reading stuff on Mad Electrical website. They seem to know their stuff.
Great idea on heat shield. Will check out the 80's trucks. Our local jyard usually has a good selection of everything.
Ive had my battery in the trunk since I built the car as well... I've had no issues with that set up and the remote solenoid, just make sure you have good ground straps.
When I had a starter rebuilt for the 454 in my convertible, they included a high temperature solenoid. It has never let me down, even spun the car over when the temp gauge was pinned while on Interstate 15 through Las Vegas in a traffic jam caused by a fatality accident.
